21 Claims. (Cl. 129--16.7)

This invention relates to improvements in an index card structure.

An object of the invention is to provide an improved index card and associated indicator means 6 of simple and inexpensive construction.

Another object is to provide a card structure of the above character in `which the movable parts Aare protected from breakage and mutilation without the use of complicated and expen- 10 sive attachments. l

Another object is to provide a device of the above character wherein the parts are so arranged as to effectively preclude accidental disarrangement thereof resulting in inaccuracies in 16 the record desired to be kept.

These and other objects are attained by the means described herein and disclosed in the accompanying drawing, in which:

F18. l is a plan view of the Vfront of the m- Fig. 2 is a viewsimilar to Fig. 1, the front cover or record portion thereof being removed.

Fig. 3 is an enlarged cross-sectional view taken online3,3ofFig.2.

The improved card comprises a rectangular sheet, suitably slitted and perforated, and folded twice upon itself to provide the front record portion 4, an inner depending short flap 5, and a back 6. The members 4, 5 and 6 each are per- 3 forated as at '1, through which perforations are threaded, in a certain manner to be described, a

spring-metal card-mounting rod Vor bar 8 the opposite ends 9 of which-extend beyond the side edges of the card structure. The mounting bar lor rod preferably, though not necessarily, is of flat material, and its ends are adapted to be received in suitable aligned openings in the opposite sides of an index card holder, in a manner well known.

Betweeny the front record portion 4 and the back 6 is disposed for sliding movement a slide or indicator member 10 which has but one accessible part, a tab 11. The tab preferablyv is integral with the slide and it extends upwardly through a longitudinal slit 12 in the record portion 4. The slit extends longitudinally of, and preferably in parallelism with, the top edge 13 of the record portion 4. kThe tab is of such height that it nearly reaches the upper edge 13.

It is to be noted that the bar 8 is so threaded through the perforations-'Tof each portion 4, 5 and 6, as to cover the top edge 14 of the tab thereby precluding any tendency of the tab to turn 55 forwardly and become mutilated when in use.

The exposed portion ofthe tab is large enough to permit use of a lead pencil eraser in moving the tab from one side of the card toward the other side thereof. c,

The tab beingattached to or integral with the slide 10,-the slide will move bodily with the tab. 60

'Ihe slide is guided in its sidewise movement by means of a pair of opposed tongues 15 formed in the slide by slittingthe slide as at. 16 in the direction of-itsmovement and then formingthe parallel transverse slits 17 and 18 at the ends of slit 16. At the four ends of slits 17 and 18are out-out portions 19 which preclude binding at ,the ends of the slits and thereby facilitate sliding movement of the slide.

, Thetongues 15 are adapted to be placed behind agude 20 formed by slitting the flap 5 longitudinally thereof at 23, at a distance from its lower edge 21'substantially equal to ythelengthA of slits 1'7 and 18. The ltongues may be disposed behind theguide 20 asindicatedin Figs. 2 and 3,l 7'5 'and itv should readily be apparent that the slide connection thereby.' provided will not permit fof cooking or wobbling of the slide. It is to be. noted particularlyvthat the short parallel edges 22 adjacent ,the out-out portions 19 ride upon the edges 21 and 23 of the guide 20 in nearly the same plane, wherefore the ends of slits 17 and 18 are not subjected to cutting action of the edges 2l. and 23 when the yparts are relatively moved. The fact that the construction` permits the use of a large slide, of approximatelyone-third or onehalf the area of the'card, lends great stability to the slide and assists in decreasing the liability of the slide to wobble. n

Extending upwardly from the slide 10, on each side of the tab, are the projections 24 .which entera slit 25 located adjacent to the bases of the tab and projections.v This slit is parallel to slit 23 and the topedgeofthe card. The extensions 24 t in the fold .between the members 5 and 6"and are subjected to the yielding force of the barv 8 when threaded through the openingsr 7. These extensions and tab 11, in the before-mentioned cooperative relationship with bar 8, serve to preclude accidental displacement of the slide when'the index card is in use.

Extending from the lbottom edge of the slide is a marker portion 26, havingan indicator 2'7 which may be a mark printed, painted or otherwise applied tothe marker portion. .The marker portion 26 depends to a point closely adjacent the line of juncture of members 4 and 6. The indicator' is rendered visible through each of a series of perforations or windows 28 in the record or cover portion4, lby moving the slide 10. @The perforations 28 may be of any desired shape or spacing. In the drawing, each perforation or window is of the shape of a parallelogram, and each'is disposed obliquely to the bottom` edge of the card.` One end of each perforation is located directly above and in spaced relation with one end of the next succeeding perforation, and all are parallel to one another. By this means of locating the perforations, they are suiiiciently separated from one another to preclude matev riallyweakening the sheet in that region, and in addition, a maximum of indicating space is obtainablein the least amount of space. Itis advantageous in most instances to overlap adjacent index cards as much as possible so as to conserve space, and for that reason the openings 28 are arranged as shown and described. 'Ihis is thereby accomplished without unduly weakening the card.

- The openings may have any desired relation-` ever, to adapt the device for various uses. The

material of which the device is constructed may vary' also, and an advantage of the structure is that both the card and slide may be vmade of ordinary paper, and not necessarily of stiff mate-v rial. In fact, the devices of this invention now in use are of ordinary writing paper, and they are very inexpensively manufactured. The fact that the construction permits the use of a large slide of comparatively light weight material and of approximately one-third or one-half the area of the area of the card, lends vgreat stability to the slide and assists in decreasing the liability of the slide to wobble.
